This will print any lines that contain non-tab characters. A line that has only tabs in it should be ignored...
Code:
awk '/[^\t]/' filename

This one left me with a file full of tabs and nothing else.

XmTabListReplacePositions(library call) 								   XmTabListReplacePositions(library call)

NAME
XmTabListReplacePositions -- A convenience function that creates a new tab list with replacement tabs SYNOPSIS
#include <Xm/Xm.h> XmTabList XmTabListReplacePositions( XmTabList oldlist, Cardinal *position_list, XmTab *tabs, Cardinal tab_count); DESCRIPTION
XmTabListReplacePositions creates a new tab list that contains the contents of oldlist, but with the tabs at the positions in position_list replaced with copies of the corresponding tabs in tabs. A warning message is displayed if a specified position is invalid; for example, if the value is a number greater than the number of tabs in the tab list. This function deallocates the original tab list after extracting the required information. It is the caller's responsibility to free the tabs in tabs by using the XmTabFree function. oldlist Specifies the tab list. The function deallocates the tab list after extracting the required information. position_list Specifies an array of positions of the tabs to be replaced. The position of the first tab is 0 (zero), the position of the second tab is 1, and so on. tabs Specifies an array of the replacement tabs. tab_count Specifies the number of elements in position_list and tabs. RETURN
If tabs, oldlist, or position_list is NULL, or tab_count is 0 (zero), returns oldlist. Otherwise, this function returns the new tab list. The function allocates space to hold the returned tab list. The application is responsible for managing the allocated space. The applica- tion can recover the allocated space by calling XmTabListFree. RELATED
